Demi Lovato has reassured fans that her recent health scare is nothing to worry about and that she's now focusing on her health and happiness.

The 22-year-old told US channel Extra tv that the hype surrounding her being rushed to hospital was worrying but nothing serious.

She said: “There was an Urgent Care next to the ER. I just went there because I wasn’t feeling good. I was not rushed to the hospital… I was pretty sick, but I was not rushed to the hospital.”

Stepping out at Universal Studios in Hollywood the Let It Go singer looked trim in her leather pencil skirt and grey t-shirt and was clearly smitten with her fluffy white puppy Buddy, who was also dressed for the occasion in a miniature black waistcoat.

Demi told Extra tv: "We're still in the process of potty training. I bring him everywhere with me."

Speaking about her recent 'thigh gap' tweet where she told fans it wasn't necessary for women to have one to be sexy, she said: “I keep hearing this term 'thigh gap’ in social media and everything.

"I feel like when we hear things as woman and men, too but specifically women with this thigh gap thing, when we hear things over and over again we start to believe that’s what beautiful means.

"It’s having this perfect beautiful, unattainable body. If you have one naturally that’s great… but for people that don’t naturally have it, I just wanted to remind them that you don’t need that to feel beautiful.”
